LORING DANFORTH, OF BUFFALO, NEW YORK.

MACHINE FOR MAKING BOOK-COVERS.

i Specification of Letters Patent No.` 10,961, dated May 23, 1854 i Toall 'whom it may concern: y

Be it known that I, LORING DANFORTH, of Buffalo, in the county of Erieand State of New York, have invented a new and useful Machine for @theManufacture of Book Covers or Cases; and I do hereby declare that thefollowing is a `full and exact description thereof, reference being hadto the `accompanying drawings and to the letters` of referencemarkedthereon. y( i The nature of my invention consists in combining a pair offolders having two distinct movements; the edge of the one being thecenterofmotion of the other so as to produce a perpendicular andparallel motion chine with part of the bed plate D, removed or broken toshow the folders A and B, with the lifter C. Fig. II is a transversesection` representing the operation of the machine. Fig. III representsthe bed plat-e D, with the folders A and B at rest. Fig. IIII representsthe position of the folders at rest with A the machinery that connectsand detaches the folders when used. Fig. V shows the position of thefolder B, whennearly perpendicular and at the time when the two Inotionsare detached or separated. `F ig. VI represents the position of the twofoldersA and B, when the surface of the folder B, is perpendicular andthe plain surface of A, is parallel to the bed plate D and the movementis complete.

The folders A and B are united at the ends in such a manner that thecenter of motion of the folder A, Fig. VI, is the acute angle of thefolder B, as shown in the same figure and both are so connected by meansof the latchet J that they move together until the pivot F, Fig. IIII,of the latchet J strikes the pivot E, Figs. l and 5, init-hel bearer Kwhen the folder A is allowed to move onward as in Fig. VI till its planesurface is parallel to the bed plate D.

When used the book cover is placed upon the surface of the `bed plate D,Fig. II (which bed plateY may be elevated or depressed by means of thethumbscrews G, according as the work to be done isthick or thin), withthe edge of the cover resting upon the surfaces of the two folders A andB, and by the connecting machinery the lifter O, is elevated until thesurfaceof the folder B (Fig.` VI) is perpendicular with the bed plate Dand against the edge of the book cover L, when by `means of the pivot E,Fig. V, striking the point F the latchet J (connected with the folder A)is detached from the pivot H (connected with the folder B) l and thefolder A, passes onward until its plane surface is parallel to the bedplate D and the work is complete as in Fig. VI.

What I claim as my invention is- The combination and connection vof themotions of the two folders A and B, in such a manner that theirmovements may be used.`

upon the edge of any material such as a piece -of junkboard, wood, orother substance,` to fold the cloth leather or paper and form a true;angular; and even edge in the manner and for the purposes hereindescribed and represented.
